134 | =head1 DESCRIPTION |
135 | |
136 | Moose. |
137 | |
138 | =head1 INTERFACE |
139 | |
140 | =head2 meta -> Mouse::Class |
141 | |
142 | Returns this class' metaclass instance. |
143 | |
144 | =head2 extends superclasses |
145 | |
146 | Sets this class' superclasses. |
147 | |
148 | =head2 has (name|names) => parameters |
149 | |
150 | Adds an attribute (or if passed an arrayref of names, multiple attributes) to |
151 | this class. |
152 | |
153 | =head2 confess error -> BOOM |
154 | |
155 | L<Carp/confess> for your convenience. |
156 | |
157 | =head2 blessed value -> ClassName | undef |
158 | |
159 | L<Scalar::Util/blessed> for your convenience. |
160 | |
161 | =head1 MISC |
162 | |
163 | =head2 import |
164 | |
6caea456 |
165 | Importing Mouse will default your class' superclass list to L<Mouse::Object>. |
c3398f5b |
166 | You may use L</extends> to replace the superclass list. |
167 | |
168 | =head2 unimport |
169 | |
170 | Please unimport Mouse so that if someone calls one of the keywords (such as |
171 | L</extends>) it will break loudly instead breaking subtly. |
172 | |
173 | =head1 FUNCTIONS |
174 | |
175 | =head2 load_class Class::Name |
176 | |
6caea456 |
177 | This will load a given C<Class::Name> (or die if it's not loadable). |
c3398f5b |
178 | This function can be used in place of tricks like |
179 | C<eval "use $module"> or using C<require>. |
